Description

Description générale

Certipur^® certified secondary standard reference buffers are used to precisely calibrate and monitor pH measurement instruments and buffer solutions. They are quality controlled and qualified in our ISO/IEC 17025 and 17034 accredited calibration laboratories against certified primary standard reference materials (SRM) in compliance with DIN 19266, IUPAC, NIST, Ph. Eur. and USP. Certipur^® reference materials offer maximum accuracy, reliability and convenience and help avoid costly repeat analyses.
